8:05 a.m. update: Jamming up on 169 in Minnetonka, Hopkins

A slow-to-clear crash involving several vehicles on southbound Hwy. 169 at Minnetonka Blvd. is creating quite a jam. Traffic grinds to a halt as far back as Plymouth Avenue. If you can, use Hwy. 100. It's moving much better.

The City of Minneapolis will station traffic control agents along Hennepin and Lyndale avenues near the Walker Art Center during the Monday afternoon rush hour to help keep intersections open and traffic moving, a city spokeswoman said.

Construction on mainline routes rolls on but the biggest snags may be on local streets leading to parties, festivals and sporting events across the Twin Cities. Meanwhile light-rail trains won't roll in downtown Minneapolis.
